Ko uvozi dizelasa iz DE, verovatno je "apdejtovan", znaci EGR, DPF i potencijalno dizne u problemu.

Diesel Cars Are Cleaner Than Some EVs, New Study Suggests
https://interestingengineering.com/dies ... y-suggests
Germany's top auto industry consultancy claims it would take more than 10 years for an electric car in the country to break even with an efficient combustion engine’s overall emissions.
The last few years have seen a clear rise in electric vehicles (EVs) with even the world's biggest conventional automakers making plans to go electric. Increasingly, more and more industry experts are speculating we may see a switch to a 100% EV adaption sooner than we think.
Among the many reasons for choosing EVs, perhaps the most compelling one is their universally acknowledged environmentally friendly nature, a much-desired trait in a world threatened by impending climate change.
Now, German automotive consultancy Berylls Strategy Advisors, which describes itself as the "only relevant top management consulting firm working exclusively for the auto industry," is saying EVs may not be the eco-friendly champions the world so desperately needs.
Polluting EV batteries
Before you worry that these electric dream machines may actually release carbon emissions, rest assured this is not the case. Rather the environmental weakness of these cars lies in the production of their lithium-ion batteries, states the consultancy's new research.
Depending on where EVs are manufactured, the energy required to make their batteries results in a high carbon footprint. So high in fact that the automotive experts estimate that an "electric vehicle in Germany would take more than 10 years to break even with an efficient combustion engine’s emissions."
"Electric cars appear to be the panacea and reduce emissions by 35 %. After all, electric vehicles do not emit any carbon dioxide while driving – at least that is a widely held opinion," said Dr Jan Burgard, managing partner at Berylls in a LinkedIn statement.
"However, from well to wheel, they do not really improve the situation. After all, electricity generation – including for electric cars – is still strongly dependent on fossil fuels in many EU countries. The climate does not care whether carbon dioxide comes from the exhaust pipe or whether it is released when lignite is burned to generate electricity or in energy-intensive battery production," added Burgard.
Diesel engine demonized?
According to Berrylls' study, building a 500 kilograms (1,100 pounds) EV car battery or bigger in a fossil fuel-powered factory would result in up to 74% more carbon emissions than producing an efficient traditional vehicle. And Burgard feels it is time to consider the diesel approach if we want to reach the 2030 EU CO2 targets.
"I miss a technology-agnostic discussion of available solutions, which also includes the potential of the currently demonized diesel engine. We will need it in order to achieve the EU's climate targets," argued the partner.
Others, however, are not convinced of the research's legitimacy. The report has already started seeing some backlash with many taking to Twitter to say the consultancy is biased considering where its funding comes from.
"Berylls Strategy Advisors, which argues that for now, drivers in Germany or Poland may still be better off with an efficient diesel engine." Who funds Berylls Strategy Advisors? This is a whole new level of mental gymnastics.

However, it may be worthwhile to consider how dirty the battery making process really is and implementing appropriate adjustments. With energy companies moving toward greener initiatives, a clean battery producing journey may be possible soon, making EVs the true environmental heroes they are meant to be!

Histerija zbog dizelaša: Suludo, "masovni ubica"
To je postala prava histerija, smatra Henrik Beme. I da podsetimo: to je ključna grana industrija u Nemačkoj.
Da li će vatrogasci, kad ih pozovemo, da dođu tramvajem? Jer i njihova vozila su isto na dizel, pa će i njima da ude zabranjen saobraćaj u stambenim četvrtima. Ili ćemo možda da imamo sistem kao svojevremeno u DDR-u? Tamo su političke birokrate odlučivale o tome kako će narod da se kreće. Socijalističkom trudbeniku nije potrebno nikakvo individualno sredstvo prevoza. Kolektivni prevoz železnicom ili autobusom – uz odu avangardi radničke klase – sasvim je dovoljan. Automobili se jesu proizvodili – iz Cvikau potiče i jedan „Horch“ ili „Auto Union“ (nakon bekstva u Ingloštat nazvao se „Audi“ – ali u socijalizmu nije bilo mesta za takve tradicijama. Već samo za Trabant.

VELEOBRT: Novi dizelaši daleko čistiji od benzinaca
http://mondo.rs/a1169368/Auto/Vesti/Nov ... troen.html
Novi modeli sa dizel motorima izbacuju manje azotnih oksida od benzinaca
Anti-dizel histerija prošle godine je doživela svoj vrhunac, što je uticalo da se samo 36 odsto evropskih kupaca počasti novim dizelašom. Frapantan je podatak da je prodaja automobila sa ovom vrstom motora pala u poslednje godine za čak 15 odsto.
Prodajne prognoze nisu dobre za naredni period, a neki analitičari smatraju da će udeo dizelaša pasti ispod 5 odsto u narednih deset godina.
ALI…
Najnovija testiranja, koje je sproveo Nemački auto-moto klub (ADAC), pokazuju da novi dizelaši emituju neverovatno malu količinu azotnih oksida (NOx), ako ih uopšte i emituju, kao i slučaju "mercedesa C220d" (0 mg NOx/km).
Još neki modeli su postigli ekstremne vrednosti. "BMW 520d karavan", "opel astra 1.6D" su izbacili samo 1 mg NOx po kilometru, "BMW 520d Steptronic" 5 mg NOx/km, a "sitroen berlingo BlueHDI 130" 7 mg NOx/km.
Kao najveći problem dizel motora apostrofirani su azotni oksidi, nusprodukt sagorevanja ovog goriva. Ovi gasovi su najveći krivci za brojna oboljenja respiratornih organa, kao i prevremenu smrt desetina hiljada ljudi širom sveta.
Zvuči neverovatno da su u nekim slučajevima pojedini dizel modeli izbacivali manje azotnih-oksida od svojih benzinskim parnjaka.
Inače, zbog pada prodaje dizelaša, prvi put u poslednjih deset godina u Evropi porastao je nivo emisije ugljen dioksida kod novih automobila. U 2017. dizelaši su emitovali 117,9 g CO2/km, a benzinci 123,4 g CO2/km. Ova prednost na strani novih dizela je posebno zanimljiva ako se zna da su ovi motori, u proseku, snažniji od benzinskih – 142 u odnosu na 123 KS.
Naverovatni rezultati ADAC-ovog testiranja posledica suprimenjene tehnologije koju je kompanija Boš najavila pre nepunih godinu dana.
Iz Boša su tada najavili da će nova tehnologija, koja je namenjena novim EURO 6d agregatima, softverskom nadgradnjom smanjiti emisiju azotnih oksida za čak više 90 odsto u odnosu na postojeće stanje. Bošova "laboratorijska" vozila postigla su tada rezultat od samo 13 miligrama NOx po kilometru i mereno u novom RDE ciklusu.
Ista tehniku merenja su primenili i ADAC-ovi stručnjaci.
Mercedes je ovakav rezultat objasnio "posebnom obradom i višestrukom recirkulacijom izduvnih gasova" na njihovom motoru OM 654, prenosi britanski Auto Express. "Naš cilj je da do 2020. dostignemo prosečan nivo od 30 mg NOx po pređenom kilometru, mereno po RDE ciklusu."
Prema aktuelnom EURO 6d-TEMP standardu, maksimalni nivo emisije azotnih oksida, prilikom RDE testiranja, iznosi 168 mg/km, koji će se od januara 2020. spustiti na 120 mg/km.
Čak je moguće da će ova norma pasti i na samo 80 mg NOx/km, jer je krajem 2018. godine Evropski sud pravde presudio da Evropska komisija nema pravo na određenje faktore usklađenosti, koji je omogućena viša granica. Najavljeno je da će se EK žaliti na tu presudu.
Sve ovo ipak neće uticati da se smanji najezda starijih polovnih dizelaša na istočnu Evropu i Srbiju.

Dok ne vidim da traže pare nazad od amera, ovo su sve prazne priče jer bi to jedino de fakto značilo da je "merenje" bilo pogrešno..
što znači da su do sad bili praktično nepismeni čim su uspeli zamenom softvera da izmene sagorevanje, pa lolsoftverskom nadgradnjom smanjiti emisiju azotnih oksida za čak više 90 odsto ...

Što nas uz one, generaciju stare automobile, bez EGR-a, DFP-a i ostalih "savremenih" tehnologija, ovde ne dodiruje ni malo. Pogotovo što se na tehničkom ni ne mere izduvni gasovi inače bi 95% voznog parka bilo isključeno.Sve ovo ipak neće uticati da se smanji najezda starijih polovnih dizelaša na istočnu Evropu i Srbiju.

Fiat Chrysler to pay Tesla hundreds of millions of euros to pool fleet
https://www.reuters.com/article/us-fiat ... SKCN1RJ03I
Italian carmaker Fiat Chrysler Automobiles NV (FCA) has agreed to pay electric carmaker Tesla Inc hundreds of millions of euros so that the vehicles of Tesla are counted in its fleet to avoid fines for violating new European Union emission rules, the Financial Times reported on Sunday.
The step will let the Italian carmaker offset carbon dioxide emissions from its cars against Tesla’s, by bringing down its average figure to a permissible level, the FT said.
The report did not mention further financial details of the specific amount that Fiat Chrysler has agreed to pay Tesla.
The Italian carmaker formed an open pool with Tesla on Feb. 25, the report added, citing a declaration with the European Commission.
Tesla did not immediately respond to a request for comment on Sunday. Fiat Chrysler did not directly address the amount that it would pay but added it would “optimize the options for compliance that the regulations offer.”
“FCA is committed to reducing the emissions of all our products...The purchase pool provides flexibility to deliver products our customers are willing to buy while managing compliance with the lowest cost approach,” FCA added in a statement.
